WINDOW-OPERATING DEVICE.

Application filed. July 9,

To all whom it mag concern:

- Be it known that SAMUEL T. MCCLARREN, a citizen of the United States of America, residing at St. Petersburg, in the county of Pinellas and State of Florida, has invented new and useful Improvements in Window- Operatin Devices, of which the following is aspeci cation. r

The object of the invention is to provide a comparatively simple and eificient means for operating and locking both in closed and in adjusted open positions a casement or hinged window or door or like closure whether suspended for vertical or horizontal swinging movement, under conditions minimizing the risk of releasing the window or closure and thereby endangering the glazing while providing for attachment to the casing with the minimum of cutting or modification thereof; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1 is a horizontal sectional view of a window casing showing a holding apparatus embodying the invention applied in the operative position thereto, the window being shown in its closed position and locked against opening from the outside.

igure 2 is a similar view showing the window held in an open position.

Figure 3 is a vertical section showing the apparatus in "elevation, the window being shown closed.

Figure 4 is a sectional view on the plane indicated by the line 4-4 of Figure 3.

Figure 5 is a plan view of the guide showing the adjacent portion of the operating.

arm or lever and the auxiliary lock.

Figure 6 is a perspective view of the 'de. l Figure 7 is a similar view of the auxiliary lock.

Figure 8 is a detail section on the plane indicated by the line 88 of Figure 4 showing the lower edge of the ;screen frame and the strip upon which it is seated.

Figure 9 is a detail view of the catch for locking the operating arm or lever.

Figure 10 1s a similar view of the operat in arm.

he 0 crating arm or lever-11 which is preferab y curved as indicated .at 11 to permit of the body portion thereof occupy- .mg a position substantially parallel with 1921. Serial No. 483,523.

the window sill12 when the sash 13 is in the closed position indicated in Figure 1, is connected hingedly with the sash through the agency of a hook 14 or its equivalent having a stud 15 for engagement by an obliquely disposed slot'16 in the operating lever, said slot erforming the function of a cam which a ords anincreased leverage of the operating arm upon the sash in starting the movement of the latter either from a closed or from an open position, but more especially from a closed position as when the sash resists movement by reason of frost or of the swelling of the woodwork. The operating arm extends through a guide 17, shown in detail in Figure 6, and consisting of a base plate 18 spanned by a bar 19, the end walls 20 of the guide being beveled or arranged upon converging lines, The end of the lever which is connected with the sash is provided with an actuating. spring 22 serving to hold the latter with the stud at one end of the cam slot 16.

.The upper wall of the guide represented by the bar 19 may be provided at its under surface with a web or'cam 23 formed by indenting or depressing a portion of the bar, or in any other suitable manner, for the purpose of clamping the operating arm or lever when the latter is drawn toward one end of the guide while relieving pressure thereonwhen the arm is moved in the other direction so as to permit of the free sliding movement of the arm when the sash is being adjusted while permitting the looking of the sash in the adjusted position merely by swinging the inner end .of the arm toward the depressed end of the wedge or cam andthus causing the frictional engagement thereof when 'the sash is in the desired position.

In the construction illustrated the ide plate is arranged in the plane of an ex-" tends through the seating strip 24 Provided for the lower edge of the screen rame 25 so as to permit of the adjustment of the sash without disturbing or moving the screen and when the sash is in its closed position it is permanently locked by engaging the operating arm or lever with a catch 26, shown in detail in Figure 9 and consisting of a plate having an u turned ear v27 over which the free inner on of the operating arm ma be 'sprun by a slight u ward bending thereof. Tl ie arm obvious y will be held in engagement with the catch,

against accidental displacement, by its res'ilience.

Themeans for locking the operating arm and hence the sash consists of a disk 28 pivotally mounted upon the base plate of theguide and having wedges 29 adapted tobe forced under the operating arm, the lat ter normally operating between said wedges as indicated in Figure 5, and said disk being provided with an operating finger 30 having an upturned terminal ear 31.

Seated upon the guide 17 isa top plate 32 having a downturned inner flange 33 and an upturned outer flange 3 adapted to bear against thev outer surface of the screen frame. Also as a further means of reinforcing the parts when the sash is in the closed position the hook shank 14 may be let into a groove 35 in the surface of the window sill, and therefore when the inner end of the operating arm or lever has been released from the catch 26 and the inward strain is applied thereto in an efiort to start the sash from its seat in the casing, the action of the cam slot 16 upon the stud 15 will not tend to laterally displace or bend the hook but will ensure the pressure due to the increased leverage bein applied in the direction of the opening 0? thesash so as to overcome any resistance which may be oifered thereby due to freezing or swellilaving described the invention, what is claimed as new and useful is 1. A. sash operating device having an operating arm or lever pivotally connected with the sash, a stationary guide on the easing through which the said arm or lever slides and means for locking the arm or lever in its adjusted positions, said means neaassi consisting of a cam disposed in contacting relation with a portion of the guide, the pivotal connection between "the operating arm and the sash consisting of a stud on the latter and an obliquely disposed slot in the former, said end of the-arm being yieldiiligly held with the stud in one end of the s 0t.

2. A sash operating device having an operating arm or lever pivotally connected with the sash, a stationary guide on the casing through which the said arm or lever slides and means for locking the arm or lever in its adjusted positions, said means consisting of a cam disposed in contacting relation with a portion of the guide, the pivotal connection between the operating arm and the sash consisting of a stud on the latter and an obliquely disposed slot on the former, a spring being connected with the lever for yieldingly holding the same in its normal positionwith relation to the stud.

3. A sash operating device having an operating arm or lever pivotally connected with the sash, a stationary guide on the casing through which the said arm or lever slides, and means for locking the arm or lever in its adjusted positions, said means consisting of a cam disposed in contacting relation with a portion of the guide and comprising a diskpivotally mounted in the guideand having spaced wedges between which the arm travels and which are adapted to be forced under the arm to move the latter into engagement with the upper wall of the guide. 7
